WebApr 17, 2024 · How do Decision Tree Classifiers Work? Decision trees work by splitting data into a series of binary decisions. These decisions allow you to traverse down the tree based on these decisions. You continue moving through the decisions until you end at a leaf node, which will return the predicted classification. WebApr 13, 2024 · Regression trees are different in that they aim to predict an outcome that can be considered a real number (e.g. the price of a house, or the height of an individual). The term “regression” may sound familiar to you, and it should be. We see the term present itself in a very popular statistical technique called linear regression.
